The simulated results show that the absorption rate of the absorber is greater than 90% in a frequency range of 24.1\u201342.6 GHz, and the relative absorption bandwidth is up to 55.47%. The thickness of the structure is 1.2 mm, which is 0.088 \u03bb and 0.156 \u03bb for the lowest and highest frequencies, respectively. The power loss density is analyzed to explore the mechanism of the absorption and the resistive film layer is important for the wideband absorption. Meanwhile, a strong absorption for oblique incidence with wide angle and the characteristics of polarization insensitivity are achieved for the proposed design.<\/jats:p>","DOI":"10.3390\/sym14061148","type":"journal-article","created":{"date-parts":[[2022,6,2]],"date-time":"2022-06-02T04:46:23Z","timestamp":1654145183000},"page":"1148","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["A Wideband and Ultra-Thin Metamaterial Absorber Based on Resistive FSS"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2702-8471","authenticated-orcid":false,"given":"Zhongliang","family":"Lv","sequence":"first","affiliation":[{"name":"College of Mechanical and Power Engineering, Chongqing University of Science and Technology, Chongqing 401331, China"}]},{"given":"Zelun","family":"Li","sequence":"additional","affiliation":[{"name":"College of Mechanical and Power Engineering, Chongqing University of Science and Technology, Chongqing 401331, China"}]},{"given":"Yu","family":"Han","sequence":"additional","affiliation":[{"name":"College of Mechanical and Power Engineering, Chongqing University of Science and Technology, Chongqing 401331, China"}]},{"given":"Yujiang","family":"Cao","sequence":"additional","affiliation":[{"name":"College of Mechanical and Power Engineering, Chongqing University of Science and Technology, Chongqing 401331, China"}]},{"given":"Lin","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Mechanical and Power Engineering, Chongqing University of Science and Technology, Chongqing 401331, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"788","DOI":"10.1126\/science.1096796","article-title":"Metamaterials and negative refractive index","volume":"305","author":"Smith","year":"2004","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.pquantelec.2014.10.001","article-title":"Hyperbolic metamaterials and their applications","volume":"40","author":"Ferrari","year":"2015","journal-title":"Prog.
